Keith Brown has written to Sky News today demanding Nicola Sturgeon appear in a TV debate they are planning on the Brexit deal.

The SNP depute leader wrote to bosses at the station this morning after it emerged they were pushing for a "head to head" discussion between Theresa May and Jeremy Corbyn.

"It is with concern and disappointment that we understand Sky News appear to be pushing to broadcast a head-to-head debate between Theresa May and Jeremy Corbyn," he said.

"The Prime Minister and leader of the opposition only represent the views of a limited share of the British public on this issue. Equally the idea that this is a binary choice between a Tory hard Brexit or a Labour hard Brexit is misleading.

As other broadcasters have noted, SNP Leader and First Minister of Scotland Nicola Sturgeon should be a part of any live televised debate. "

He continued: "It is vital that people across the UK are able to see all of the options that are being put forward - including the SNP’s position for the whole UK to maintain membership of the Customs Union and Single Market in order to protect jobs and the economy - so all options are properly discussed and scrutinised.

"As the third party at Westminster, the second largest party across the UK in terms of membership and as the party of government in Scotland the SNP need to be represented in any leaders’ debate."

Corbyn has said he would "relish" a TV debate with Theresa May after it emerged she is ready to go head-to-head with the opposition leader over her Brexit deal.

May stayed away from TV debates with the Labour leader ahead of the general election last year.

The Daily Telegraph reported today the Prime Minister is gearing up to take on the Labour leader ahead of a crucial Commons vote on her agreement pencilled in for 12 December.

According to the paper, May wants a primetime Sunday night slot to take on Corbyn, who has branded the agreement "a miserable failure of negotiation" and vowed that Labour will vote against it.

A Labour spokesperson said: "Jeremy would relish a head-to-head debate with Theresa May about her botched Brexit deal and the future of our country."
